These grand giants are fun and easy to grow with dramatic results. Kids of all ages will love them! The big-framed, strong plants reach from 12 to 16 feet tall to follow the sun; their brilliant golden flower faces make the entire garden a glorious bright summer celebration. A row of 'Sunzilla' sunflowers makes a wonderful living hedge that grows before your eyes. After flower petals drop and seeds have matured, the big heads of plump kernels make a feast for neighborhood songbirds. Keep soil moist and well weeded and protect seedlings from birds with netting of plastic berry boxes, removing before plants get crowded. For large flower heads, space properly so the big plants have room to grow to full size.
